I have a Radeon X1300 PRO AGP 256M that I've been using for a little over a year now. Now all of a sudden when i try to start up my computer with the card connected all i get is a black screen. The computer just hums. No keyboard or mouse lights come on, the computer seems dead except for it has power. When i took the card out a ran my computer on the built in graphics card and did a system restore on my computer because i figured it was a virus. Everything was erased, i put the x1300 back in, started up, and got the same black screen. I've just been running on the built in card. If anyone has any ideas please let me know.
